The case for Tampa Bay Rays

Starting pitcher edge: 21 points
Leo gives Nick Martinez a 21-point edge over Shawn Armstrong, driven mainly by BB/9 (1.3 vs 4.8) and expected innings (5.8 vs 4.5).

The case for Cleveland Guardians

Late-inning bullpen advantage
Tampa Bay Rays relievers have a 5.40 ERA over the last 7 days; Cleveland Guardians relievers have a 0.59. If this is still close after six innings, that gap favors Cleveland Guardians.
Team strength favors Cleveland Guardians
Before any pitcher or bullpen adjustment, Leo's own team-strength model has Cleveland Guardians ahead (56.5% to 52.7%). The pick still comes from Tampa Bay Rays once the pitcher and bullpen terms are applied.

Why it is not official

Setup quality below the bar
Lab Rating is 4.0/10, under the 7.2/10 required for an official pick.
Own bullpen carries risk: 6.0/10
The Tampa Bay Rays bullpen comes in normal. A lead after six innings is less safe than usual.

Why the setup score is what it is

Conviction: 8.4/10
Leo's win probability for Tampa Bay Rays (71.8%) is well clear of a coin flip -- this is a real, stated lean, not a guess.
Pitching plan: 32/40
Nick Martinez rates 74 on Leo's pitcher score, judged on its own merits (50-80 is the credited range). That is a strong start on its own, and it earns most or all of the available credit here.
Offense: 0/50
Tampa Bay Rays's recent form does not clearly outpace Cleveland Guardians's.

Why the price is what it is

Team strength: 52.7%
Before any pitcher or bullpen adjustment, Leo's team-strength model alone makes Tampa Bay Rays 52.7% to win. Everything below moves the price from this starting point.
Pitcher score gap: 21 points
The pitcher-score gap favors Tampa Bay Rays by 21 points. This is the biggest single mover of the price -- a large gap moves it a lot, a small gap barely moves it.
Bullpen adjustment: -0.054
The bullpen-fatigue gap between the two pens nudges the price toward Cleveland Guardians. This moves the price less than the starting pitchers do, since a starter covers more of the game than the bullpen.
Net effect: 52.7% -> 71.8%
Team strength alone had Tampa Bay Rays at 52.7%. After the pitcher and bullpen terms, the price is 71.8% -- the same number shown as Model Lean above.
The verdict Leo passes. This is a bullpen game -- no confirmed traditional starter, so Leo does not publish an official pick here.

Risk is what the model actually uses: fatigue blended with how well the pen has pitched. High fatigue with high efficiency is a tired pen that is still getting outs.
